What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

No default rule of that graph reaches this license: it speaks about every act the rules are about.

Verdict

Record changed since this review
yes (version 2, 2026-09-24)
Findings
7 recorded, 3 applied to the record, 2 proposed

The Sun Public License is the Mozilla Public License 1.1 with a Sun-specific jurisdiction clause. It is reciprocal and it grants sublicensing. The record had both backwards: share-alike as an optional permission and sublicensing prohibited. Both were corrected and the SPDX id was added.

7 findings

  • major Rubric 5 odrl:permission applied

    Section 3.1 states that "The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2." That is a duty. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty.

  • major Rubric 3 odrl:prohibition applied

    Sections 2.1(b) and 2.2(b) grant the right to "use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications". The record prohibited odrl:grantUse. Removed the prohibition; the matching permission is held back by the same dependency-graph axiom as in OSL-3.0.

  • major Rubric 3 odrl:permission proposed

    The permission that belongs with the finding above, pending the dependency-graph decision.

  • minor Rubric 1 spdx:licenseId applied

    Added SPL-1.0. Verified rather than assumed: cc:legalcode and dct:source already point at the Open Source Initiative page for SPL-1.0 and the fetched text is the Sun Public License version 1.0.

  • minor Rubric 6 dalicc:WarrantyDisclaimer proposed

    The stored disclaimer contains the artefact "../AS IS''" where the text reads "AS IS". It comes from the source the record was built from. Correcting a published literal is left open for the association's decision.

  • gap Rubric 8 vocabulary none

    Patent grant, patent retaliation and the Sun-specific jurisdiction clause (section 11 names California law and, for Sun, the courts of Santa Clara County) have no terms. Proposed: dalicc:patentGrant, dalicc:patentRetaliationTermination.

  • info Rubric 10 family none

    This record, CommonDevelopmentAndDistributionLicense10 and CommonPublicAttributionLicenseVersion10 are all derived from the Mozilla Public License 1.1 and should model reciprocity identically. After the review this one and the Common Public Attribution record agree; the Common Development and Distribution record still permits dalicc:ChangeLicense instead.

Report an issue The review record as JSON The review checks the model against the license text. It is not legal advice.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

    The content review of 2026-09-15 added 1 identification detail and 1 license-wide duty, removed 1 permission and 1 prohibition and recorded the review state. Later changes named the license the record itself is published under.

    • added duty cc:ShareAlike

      Review finding Section 3.1 states that "The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2." That is a duty. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty.

    • removed permission cc:ShareAlike with duties [cc:Notice, cc:SourceCode]

      Review finding Section 3.1 states that "The Modifications which You create or to which You contribute are governed by the terms of this License, including without limitation Section 2.2." That is a duty. Removed the cc:ShareAlike permission and added a license-wide cc:ShareAlike duty.

    • removed prohibition odrl:grantUse

      Review finding Sections 2.1(b) and 2.2(b) grant the right to "use, reproduce, modify, display, perform, sublicense and distribute the Original Code (or portions thereof) with or without Modifications". The record prohibited odrl:grantUse. Removed the prohibition; the matching permission is held back by the same dependency-graph axiom as in OSL-3.0.

    • added spdx:licenseId "SPL-1.0"

      Review finding Added SPL-1.0. Verified rather than assumed: cc:legalcode and dct:source already point at the Open Source Initiative page for SPL-1.0 and the fetched text is the Sun Public License version 1.0.

    • added dct:license <https://creativecommons.org/licenses/by/4.0/>

      Manual edit Every record is published under CC BY 4.0. cc:license names the record DALICC keeps of that licence; dct:license now names it by the address Creative Commons publishes it at, so that a consumer matching the canonical IRI finds it.

  2. Version 1

    The version this model had before the content review of 2026-09-15.

    View JSON-LD Turtle RDF/XML

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
